Cause
This defect is caused by a paint coating being applied to a surface which has been contaminated with oil, grease, or polish causing the wet film to creep back exposing the underlying surface. This type of problem can also occur when coatings are applied to surfaces which have previously been treated with a silicone based product, contaminated with body fats including hair sprays etc. In extreme cases where the coating flows back from a large area of the surface, the term crawling is sometime used.
Once the coating has completely dried and the general adhesion is satisfactory, thoroughly flat down to a smooth surface
using wet or dry carborundum paper wet. After rinsing and ensuring the surface is free from all contaminates re-paint as required.
